I am using CD and have several questions about the pH of its designated buffers.
1. What is the pH per se of a freshly prepared 10 mM NaH2PO4 water solution ?
2. What is the pH per se of a freshly prepared 10 mM NaH2PO4 , 150 NaF water solution
3. What is the pH per se of the above solutions when Na is replaced by K.
5. What is the pH per se of a 50 mM Tris (no HCl) water solution.
4. Does the phosphate has enough ''strength ' to keep the pH constant over time, say 1-2 weeks ?
5. What is the UV cutoff of a 50 mM Tris (no HCl) water solution.
Thank you.
